Click here for the West Nile Seasonal August 14th, 2017

Based on all data available Sept. 11th, we expect to see 53 cases in SD in 2017. This is essentially unchanged from last week's prediction of 52 cases. This low number is due primarily to low mosquito infection rates in the early season, a long stretch of dry weather, and cold weather in late July, early August.
